Maintenance method of wave soldering furnace

The current electronics industry competition, a business to survive, then the enterprise is the quality of leading, how to do the quality that is the cost of materials and machinery usage and maintenance, mechanical maintenance can extend the service life to improve production quality and efficiency and utilization .
In the following, a brief description of the maintenance of the crest furnace is given.

The maintenance of the crest furnace is generally divided into four parts:
1. Wave soldering machine mechanical part: If the machine is running too long, not maintenance, check will appear loose screws, gear teeth and bad degree of bad, slow the chain speed, the drive shaft may rust caused by orbital deformation (Such as trumpet, trapezoidal and so on) will lead to board, card board phenomenon, there is poor quality after the furnace, the track level of deformation and other conditions. Both affect the performance of the machine itself and a waste of production time.

2. Wave soldering furnace spray part: If you do not spray the spray system for a long time will lead to photoelectric sensor failure, PLC program control is not accurate, synchronized with the track motor spray motor identification information is not accurate, the speed of the spray motor slow Such as failure. This failure will affect the flux spray uneven (uneven volume, may be ahead of or delayed spray), nozzle clogging, pressure is not enough, flow reduction, flux moisture and so on. Not only affected the quality of the furnace after the furnace also increased maintenance personnel. How to control the cost, how to extend the life of the machine, the use of where to talk about, it is worth pondering.

3. Electrical parts of the wave soldering furnace: If the machine is too long without maintenance, maintenance or replacement of some parts, it will produce electrical components (such as: AC contactor, relay ammeter, voltmeter, etc.), wire insulation Resistance increases, so that the conductivity is not strong, poor contact, in the power will pull the soliton, short circuit, then the circuit will multiply the current, may burn electrical parts, instruments. Do not want to make serious damage to mechanical equipment, delay production and damage to the human body is difficult to predict the consequences.

4. Wave soldering furnace heating pipe part: If the use of a long time is not on the heating pipe maintenance and replacement, there will be heating pipe heating temperature is not uniform, heat pipe aging, fracture, SMT reflow oven will affect the patch components of the melting tin Welding effect. Such as cold welding, tin beads, short and so bad, DIP wave soldering will affect the role of flux on the PCB'A (not reach the welding effect). Tin bath solder melting time is extended, due to uneven temperature lead to burst tin (due to tin in the melting when the chain burst, bearing and stuck), temperature control that is not accurate (may lead to misjudgment) and so on. This will not only guarantee the quality and waste of production time, but also increase the mechanical costs, labor costs and material costs.
